What Causes Non-Double-Couple Earthquake Sources in the Mantle?

本研究的目的是对这一现象进行系统分析， 大非双力偶中深源地震 源组件。 主要任务是确定从 以前确定的非双偶事件，无论它们是 “本质上”非双重夫妇，或者他们是否 似乎是子事件的总和，这些子事件单独似乎是 双人组。 有些事件将在一个配对中进行研究 同一地区发生的两个事件在其 非双耦合元件，以最小化路径效应 以及其他系统性差异。 真非双偶事件 将根据位置和其他系统性信息进行分类 特色 这项工作对解决这个问题有直接的应用 深源地震的起源。

The objective of this research is to make a systematic analysis of intermediate and deep earthquakes with large non-double-couple source components. The primary task is to determine from previously identified non-double-couple events whether they are "intrinsically" non-double couples, or whether instead they appear to be sums of subevents which individually appear to be double couples. Some events will be studied in a matched pair mode where two events from the same area differ markedly in their non-double-couple components in order to minimize path effect and other systematic differences. True non-double-couple events will be classified for location and other systematic characteristics. This work has direct application to the problem of the source of deep earthquakes.
